“…For this ring, the FSR (Free Spectral Range) is calculated to be 575 GHz and the round-the-ring trip delay along the ring is 1.74 ps. The bus-ring and ring-ring coupling ratios are 0.23 and 0.02645, respectively [16]. The waveguide loss is 0.2 dB/cm and the delay time through a delay waveguide is 200 ps.…”

A two-dimensional optical code division multiple access (OCDMA) en/decoder composed of four double-ring resonator add/drop filters and three delay waveguides is designed, and a transfer matrix method combined with fast Fourier transform is implemented to provide numerical simulations for the en/decoder. The auto-correlation peak level over the maximum cross-correlation level is larger than 3 at the center of the correctly decoded pulse for most of wavelength hopping and spectral phase code combinations, which assures the BER lower than 10 -3 which corresponds to the forward error correction limit.

“…A problem arises because the radiative character of coupling between dipoles complicates the task of defining a coupling coefficient between the arrays, in contrast to the well established definition of κ between optical resonators where the coupling is based on the evanescent field ( [17] and references therein). To this end, we will here investigate the success of two trial-definitions of inter-array coupling coefficient in predicting the computed round-trip phase split values, and will avoid giving a final explicit definition, which is rather difficult -if not impossible -due to the difference in the coupling mechanism in optical and RF systems.…”

“…11 in comparison with the above computed round-trip phase differences on even and odd split resonances for several minimum distances between the two arrays. There is some good agreement between the curves for A more involved definition of inter-array coupling coefficient is obtained by borrowing the model of an optical variable coupling coefficient coupler [23] which is usually applied to estimate the coupling coefficient between TW optical resonators [17]. According to this model, the mode amplitudes along the interacting region of length L, A 1 (z), A 2 (z) satisfy two coupled differential equations dA 1 /dz + jβA 1 + jκ(z)A 2 = 0 and dA 2 /dz + jβA 2 + jκ(z)A 1 = 0 where β is the propagation constant and κ(z) the variable coupling coefficient.…”

“…Similarly to circular dipole arrays, modes supported by TW resonators are also based on a constructive self-interference condition which is that the round-trip phase acquired by the trapped wave on resonance is an integer multiple of 2π. The resonances are manifested as narrow peaks in the transmitted or reflected power spectrum, which are obtained when these cavities are coupled to external waveguides in order to realize wavelength-selective filters [17].…”

Abstract-A well known property of large circular closed-loop arrays is that when the dimensions and the distance of the cylindrical dipoles are properly chosen, the arrays possess very narrow resonances. As far as single isolated loop arrays are concerned, the phenomenon has been predicted and analyzed in the past in the framework of "two-term" theory. In the present paper the same methodology is, for the first time, applied to investigate the system of two coupled identical circular arrays. It is found that the spectral profile of this new array is characterized by the coupling-induced splitting of the resonances of the single loop array into symmetric and antisymmetric supermodes, in direct analogy with other types of coupled electromagnetic cavities. Due to the circular symmetry of the individual arrays, the phenomenon is strongly correlated to the optical counterpart of two coupled traveling-wave optical resonators, such as whispering gallery or microring resonators. By borrowing the resonance splitting model from optical resonators, this analogy connection is investigated and interesting conclusions are reached.

As the transistor's feature scales down and the integration density of the monolithic circuit increases continuously, the traditional metal interconnects face significant performance limitation to meet the stringent demands of high-speed, low-power and low-latency data transmission for on-and off-chip communications. Optical technology is poised to resolve these problems. Due to the complementary metal-oxide-semiconductor (CMOS) compatible process, silicon photonics is the leading candidate technology. Silicon photonic devices and networks have been improved dramatically in recent years, with a notable increase in bandwidth from the megahertz to the multi-gigahertz regime in just over half a decade. This paper reviews the recent developments in silicon photonics for optical interconnects and summarizes the work of our laboratory in this research field. interconnects, optical technology, complementary metal-oxide-semiconductor (CMOS), silicon photonics Citation:Hu T, Qiu C, Yu P, et al.
